Abstract
A tool carrier unit, intended to be moved over a tube plate, comprises two perpendicular arms equipped with devices for engaging in the holes of the plate, and for moving the unit, step by step, by relative movement of the arms, across the plate. The unit comprises a supporting element in the form of an angle bracket defining a vee arranged with its apex perpendicular to the plate. The arms are arranged external to the vee, and at the inside of the vee, unaffected by the movement of the arms, guides are provided for supporting a tool.
